Function: trigreduce (expr, x)
Function: trigreduce (expr)
- Combines products and powers of trigonometric and hyperbolic
Example:
(%i) trigreduce(sin(x)^2);
(%o) (1-cos(2*x))/2
(%i) trigreduce(sin(x)^3);
(%o) (3*sin(x)-sin(3*x))/4
(%i) trigreduce(cos(x)^2);
(%o) (cos(2*x)+1)/2
(%i) trigreduce(cos(x)^3);
(%o) (cos(3*x)+3*cos(x))/4
(%i) trigreduce(-sin(x)^2+3*cos(x)^2+x);
(%o) cos(2*x)/2+3*(cos(2*x)/2+1/2)+x-1/2
